APP for surveying

I contacted them and was told that they could not make it work for the RS2, that they had to do some sort of update. So I am still looking for software to use with my new RS2 s.

Yes that is who I contacted, I down loaded the demo version but when I checked with them they said that there was a bluetooth connection issue that they may address in a future version of the software, so I gave up on the demo. still looking.


Survey Master is one of the best free apps. I managed to connect my RS + in two test sessions, making surveys and stakeout. This app is very professional and complete. I did it emulating the T300 Plus as seen in the image but now it doesn’t connect me anymore. Anyone who has succeeded and can help me. Thank you

I will try again and get back to you. I also found it to be a very professional feeling app.


Thanks Brent, it is very strange in my RS + that sometimes I can connect it working well and at other times most I cannot achieve it.

It turned out to connect? I did not connect RS2.

PLS try Ntrip Lefebure to fetch GPS data from Bluetooth as an substitute for phones internal GPS(mock location) and setup Survey Master App
Connection -> Device model Controller GNSS

it work only mobile phone internal GNSS not for mock location.

It is strange the steps that I follow to make the connection, but it works for me in Reach RS +, here I leave the steps, they must follow all the steps indicated, they tell me if it works for them.

Hi, i just managed to connect with rover please help on how to go about the base connection to have a fixed status.thanks

@stan29rob, you have to setup Base and Rover first before mange to connect to the application following a doc here :

Hi I have tried to use survey master. And faced 2 problems:
1.Connection to base always showed me as rover mode.
2. Any idea how to do base correction?

This doesnt work. You have to use a rover with an already FIXed solution and output this over NMEA to Survey Master
